Q: the pressure relief valve on the top of the tank needs replaced: Turn the inlet off , turn the gas off or electric, drain the tank by connecting a garden hose to the drain valve remove the pressure valve and install a new one.. Remove the hose close the drain open the pressure valve turn on the water open all of the faucets in the house to allow all of the air out of your system have some one watching the sinks it could make a mess, relight the pilot light or turn the electric back on. Remember to use a little teflon tape on the threads of the pressure valve.

Q: My car hesitates on the highway 55 m/h and up after about 20 minutes of highway driving, I unplugged the EGR valve to see if it still hesitates, but the problem went away after disconnected the Egr, so is it for sure that the valve is bad? Just wanted to make sure there's no other component that could be also be bad. I have a toyota avalon 1997.: EGR valve will cause trouble at idle, like at a stoplight, not highway speeds.

Q: I was diagnosed with Mitral Valve prolapse...I'm 21, 5.5 tall and 130lbs, I had a healthy lifestyle...my doctor said that my case isn't really sever..but i'm taking medications to keep it this way...something i cannot ask my doctor about, would intercourse be harmful to me? and how should I deal with it??? is it okay for me to have children in the future? and could my MVP be cured without surgery??: You can lead a normal health life with MVP. What it is is the valve between the left atria and left ventricle doesn't close fully like it is suppost to and some blood seeps back into the atria when the blood is being pushed out of your heart. MVP is more common then you think. The doc even said to you that your case isn't really severe. MVP cannot be cured without surgery at this time. However you'll be fine. Just keep to your doctor visits as scheduled to keep tabs on it.

Q: I started out playing trombone in middle school, then switched to euphonium as my main instrument. (I still play trombone for marching and jazz band, but I'm a little better at euphonium.) That being said, should I get rotary valve trombone or the one with axial flow? I only have a student trombone right now... And I have a professional Besson euphonium.: We had one that was hard to dial. Thought I broke the tip of my finger off! That was the day of the 5 digit phone number.

Q: Is there a difference between the atrioventricular valves in the right side versus the left side of the heart?Is there a different between the pulmonary valves?: Atrioventricular valves separate the atria and ventricles. Mitral valve has 2 flaps which separates the left atria and the left ventricle, whereas tricuspid valve has 3 flaps which separates the right atria and the right ventricle. I think there's only 1 pulmonary valve, which is located between the right ventricle and the pulmonary artery. Pulmonary valve and aortic valve, which lies between the left ventricle and the aorta, are two semilunar valves.

Q: I'm taking a pipe fitting class and I can not find witch valve had the most restriction.: I okorder /

Q: I got a french horn, but don't know if I can just use the valve oil I use for my trumpet. please help, thnx in advance :D: Simply said: nope

Q: i have a yamaha trumpet. i got it brand new and it is 3 years old. I recently did drop it and i have a tiny dent on the last turn to the bell. after that they started sticking . There are no dents on the valves or casing surrounding them. i brought them to Quinlan and fabish and showed them the sticking they replaced the valves spring padding and the such. They also did an ultrasound cleaning i think it is called . they are still sticking. Please any think that you can suggest i showed my band teacher who suggested going to Quinlan and fabish. Then my trumpet teacher who said i need to oil more after the cleaning please help: Check that you are not putting sideways pressure on your valves when you press them downwards. Even on a good horn this sideways pressure can cause friction between the piston and the valve casing. Avoid this by arching your fingers a little, depressing with your finger's tips, and avoid the pinkie finger ring entirely. Tying your pinkie up in that only restricts your 3rd. finger's freedom of straight downward movement. Over- lubricating the valves can be as bad as too little oil. Do the whole warm bath treatment that you would normally do to clean it, add 3 drops to each valve, work horn for a few minutes, wipe valves with very old (washed heaps of times) t-shirt: then finally 2 drops again. If this doesn't work, get a trumpet specialist teacher to take it home for this treatment.(You might not be bathing it right). Failing that, check my web site's repair section. Good Luck!

Q: Hi all,My buddys ford 460 has stuck valves. Where do I start? Could I notice anything by removing the valve covers, or do I have to remove the heads? Is it possible to unstick them without removing the heads? Assuming they stuck from sitting. What's the chance it bent the pushrods if it was running when they stuck? Can I check this without removing the heads? I'm not too familiar with this engine.: Stuck okorder /

Q: The water inlet valve on my Kenmore washer leaks. Is there an easy way to replace it? Last time it broke they charged me over $100 to fix it.: Do a Search Kenmore inlet valve. very cheap. or better yet go to Home Depot and pick one up if your warranty has run out. They will soak u for labor everytime when u can easily fix it yourself.
